In printing plate production for planography, our main focuses are offset lithography and waterless lithography.
In planographic printing, the printing and non-printing elements lie on the same plane. This print method relies on the different physical properties of oil and water to separate the printing and non-printing surfaces. (Here a distinction is made between offset printing and waterless printing.) Printing works because the ink only adheres to the greasy surfaces, while the water-containing areas repel it.
Offset printing is an indirect planographic printing method. The printing and non-printing areas are separated at a physical level. The non-printing elements of the printing plate are hydrophilic (water loving), while the printing elements are oleophilic (hydrophobic, or water repellent). The film of fountain solution created in this process prevents the ink from adhering to the non-printing areas. The process uses paste inks, which are transferred onto the substrate using a plate cylinder and a rubber blanket.
Offset printing offers a wide range of high-quality, printable substrates, and the comparatively fast and economical plate production makes it possible to print premium packaging.

Waterless printing, or dry offset printing, is also an indirect planographic printing method. In waterless printing, the plate's surface is essentially ink repellent, for example because it is covered with a silicone layer. Based on the print image supplied, the silicone layer is removed from the plate in the image areas, defining the ink-receptive printing areas. Just as in “wet” offset printing, the printing plates are made of aluminium. Here too, printing is indirect, through the print image's transfer onto a rubber blanket and from there onto the substrate.
